Problems solved by technology

Though each refinery tries to select crudes which best meet its particular requirements, making such a selection often has undesirable cost implications.

Example

[0067]Refinery planners at company downstream locations run weekly linear program models to optimize the refinery's crude slate, operation, and utilization, nominally 20 weeks in advance of the actual processing date. The base crude slate is chosen, and the linear program model is run again substituting the tailored synthetic crude for all or some of the base crude slate. The willing-to-pay-price and optimum volume are calculated. For example Refinery “A” may specify a 30 days supply of 100 MBPD 28.6 API syncrude with 10 percent bottoms, 80 percent middle distillates and gas oil, and 10 percent naphtha at $32.12 per bbl. This information would be communicated to the planner at Upgrader “1”. Simultaneously, Refinery “B” may specify a need for similar 30 days supply of 60 MBPD 36 API bottomless Synthetic Precision Crude Oil at $37.16 per bbl, and again the information is communicated to Upgrader “1” planner. Upgrader “1” is capable of producing a nominal 200 MBPD, and would run...

Abstract

The instant invention is directed to a process wherein a heavy oil feedstock upgrader alters its mode of operation of its full conversion hydroprocessing unit to create a custom tailored synthetic crude feedstock based upon data communicated from a target refinery and data communicated from the heavy oil feedstock upgrader. The data from the target refinery is data that represents refining process data and linear program modeling along with analysis by a refining planner to calculate the optimum “synthetic trim crude” that will optimize the effective use of the target refinery's capacity and equipment.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a continuous or batch process wherein a heavy oil feedstock upgrader produces a synthetic crude oil which is custom tailored to fill out a refinery's crude slate.BACKGROUND OF THE INVENTION[0002]Global energy usage continues to rise with no sign of abatement, creating a growing demand for oil resources. Light, sweet crude oil production is not increasing enough to meet this growing demand. Additionally, the reserves of light, sweet crude oil are being depleted more rapidly than new reserves are being found. To fill this gap, larger quantities of heavy oil feedstocks such as heavy crude oils or extra heavy crude oils derived from various carbonaceous resources are being brought on stream. The cost of development of these heavy crude oil resources has been decreasing over the last several decades making them more economical to recover.[0003]Heavy crudes often require some processing to reduce their viscosity and to make them...
